Hello Greg, Thank you for your comments on WCAG 2.0 [1]. Issue 492 [2] Greg Gay writes: 2.5 Required criteria for this guideline applies to success feedback as well as error feedback. When a screen reader user for instance, submits a form that performs a particular action, they will often want to verify that the operation was successful. Without success feedback it can be very time consuming to make this verification. "2. after a successful operation , provide the user with confirmation feedback". Success feedback might have its own guideline (2.6, though it might fit as 3.4 (3c)) since it is fundamentally different from error feedback, and error recovery. However, both error and success feedback could be consider "graceful recovery". We distinguish between error, warning, and success feedback in ATutor. Error messages state the problem that occurred and provide courses of action. Warnings state that a possible error has occurred and provide a means to revert to a previous state our take an alternative course of action. Success feedback provides simple confirmation (in most cases) ATutor Instructor Demo (see the feedback system as an instructor by performing various tasks such as creating, updating, or deleting content, modifying preferences, posting announcements....) http://www.atutor.ca/atutor/demo.php See "Learning from Your Mistakes" for more about fundamental cognitive differences between error and success feedback http://www.ldrc.ca/projects/projects.php?id=23 === In response to Issue 496, I wrote [3]: This guideline was significantly rewritten in the March 11, 2004 Working Draft [3]. However, the draft does not include anything about success feedback. It is not clear whether the recommendation to include this feedback is something for the guidelines or techniques. If you feel this should be included as a success criteria, please propose an edit to the latest draft. === Could you look at our latest draft [4] and write a proposed guideline or success criterion? I am happy to help you draft a proposal and am available either by telephone or email, whichever you prefer.
